applied to bull
thistle rosette in lawn. . .
12 days later, the thistle is dead
with no harm to grass even
though glyphosate is a non-selective
herbicide!

Precision System
• Less risk to desirable plants: less overspray or
drippage
• Herbicide uptake increased: foam herbicide
sticks to and dries slowly on weed tissue
• Visibility Improved: foam is easy to see
• Reduced Herbicide Waste: only apply what is
needed for the job
